Corneal Examination
In this section, using advanced facilities and equipment, a highly precise and comprehensive evaluation of the anterior segment of the eye is performed. Some of these evaluations include:
Orbscan and Pentacam
These devices provide corneal topography, which analyzes the overall structure of the cornea, including its surface power, thickness, and the shape of its anterior and posterior parts. This technique allows for the assessment of the posterior cornea as well.
Pachymetry
This method uses ultrasound waves to measure corneal thickness. Pachymetry is an essential preoperative step before refractive surgeries like LASIK, as these procedures involve removing a portion of the corneal tissue.
Topography
This technique involves projecting illuminated rings onto the corneal surface, analyzing their reflections, and generating a topographic map to detect any abnormalities such as keratoconus (corneal ectasia), corneal scarring, and corneal curvature irregularities. It is a crucial assessment for candidates considering refractive surgeries like LASIK and may also be required for postoperative follow-up in some cases.
Confoscan
This technique is used for pre-surgical corneal assessments, early detection of keratoconus, evaluation of endothelial cell health (the innermost corneal layer), determining the depth of corneal layers removed in certain surgeries, and examining the epithelial layer (the outermost corneal layer).
